Wherein m=2mv
2. matching and decoding device
We are the coded representation v based on obtained jacket and lower clothingtAnd vb, with multi-layer perception (MLP) (referred to as MLP) come pre- The matching marking between given jacket and lower clothing is surveyed, as shown in Figure 3:
Shown in specific mathematical procedure such as formula (7) and formula (8):
hr=ReLU (Wsvt+Usvb) (7)
p(rtb)=softmax (Wrhr) (8)
Wherein hr∈Rn, Ws and Us∈Rn×m, Wr∈R2×nIt is the parameter in network.P (the r finally exportedtb) it is one Probability distribution, corresponding p (rtb=0) and p (rtb=1), wherein rtb=1 indicates that given jacket and lower clothing match, and rtb=0 table Show that given jacket and lower clothing mismatch.We are by the matching degree of jacket and lower clothing, that is, p (rtb=1) it is considered as matching marking.
3. generating decoder
For the combination producing comment to given jacket and lower clothing, we used gating cycle neural networks (referred to as It is GRU) as encoder is generated, as shown in Figure 4:
We calculate the original state s of GRU with the coded representation of jacket and lower clothing first0∈Rq, as shown in formula (9):
s0=tanh (Wivt+Uivb) (9)
Wherein WiAnd Ut∈Rq×mIt is the parameter in network.Each time step τ later, we are to output before GRU input Word term vector wτ-1∈Re, current context vector ctxτ∈RDState s beforeτ-1∈RqTo calculate new shape State sτWith current output oτ∈Rq, as shown in formula (10):
sτ,oτ=GRU (wτ-1,ctxτ,sτ-1) (10)
Wherein context vector ctxτ, by it is proposed that cross-module state attention mechanism calculate.Specifically, we will The jacket visual signature and lower clothing visual signature extracted is combined, and is obtainedThen We calculate ctx to formula (13) by formula (11)τ:
Wherein Wg∈Rq×DIt is the parameter in network.By cross-module state attention mechanism, we allow generation decoder can be note Meaning power, which is placed on effective visual signature, guarantees making full use of to the visual signature of extraction.Finally we are come pre- by formula (14) It surveys current time and walks the word to be generated:
p(wτ|w1,…,wτ-1)=softmax (Wooτ+Uoctxτ) (14)
Wherein Wo∈R|V|×q, Uo∈R|V|×D, V is our dictionary.p(wτ|w1,…,wτ-1) what is returned is the τ word wτProbability distribution on entire dictionary, we take the word of maximum probability as current prediction result when prediction.If worked as Preceding prediction result is fullstop, illustrates to have generated a complete sentence, then the word generated all time steps is sequentially A sentence is connected into return.
NOR before application, needs to learn network parameter, article vector and term vector on training set.Training set by from The real user that online fashion community crawls thinks that matched jacket and the combination of lower clothing and user comment are constituted.We are logical simultaneously Negative sampling technique is crossed to obtain it is considered that unmatched jacket and the combination of lower clothing.We define loss function such as formula (15) and arrive later Shown in formula (18):
L=Lmat+Lgen+Lreg (18)
Wherein P+It is matching combination of sets, P-It is to mismatch combination of sets, CtbIt is the comment set of matching combination (t, b), Θ is Whole parameters in network and, LmatCorresponding matching loss, LgenCorresponding generational loss, LregCorresponding regularization loss.Due to not Matched combination, we do not comment on, so we do not consider generational loss therein.And from these true user comments In, NOR may learn useful clothing matching information.Then we with the common Back Propagation Algorithm of deep learning (referred to as For BP algorithm) parameter update is carried out to reduce loss to network.
After NOR training, parameter, article vector and term vector are just all fixed, and then can be used for given upper Clothing and the marking of lower clothing prediction and matching and comment generate.In clothing under recommending for given jacket, we are first with NOR to candidate Each of lower clothing calculate it and the matching of jacket is given a mark, then sorted lower clothing to obtain recommendation results according to score height. NOR also generates the reasons why comment is as recommending simultaneously.Recommend jacket similarly such for lower clothing.
